$Tesla(TSLA.US)$ Is this really going to last until 190 and then bounce back? What do you think

$NVIDIA(NVDA.US)$ , I'm talking about you
Good company, good stock, but it's too expensive to buy. What should I do?
Can I buy it? I definitely won't buy it. There is a possibility of another rise, but a negative downturn will cause the stock price to plummet. Also, it's not likely to rise much. Going from 100 to 200 is easy, and going from 200 to 400 is difficult. The profit is small, and the risk is huge.
Should I sell it? I think profits should be locked in. It would be great if I earned most of it, but how much more could it increase?
Should I go short? I won't be shorting at the moment. To use an inappropriate analogy, shorting is a bit like being a thief. Don't start when you're unsure. When can I go short? Well, we need to find something that supports the current high stock price. When it no longer exists, push the wall down and follow the trend. Only then can we buy it for zero yuan
As for when to start? Now hyping up NVDA, isn't it just copying the AI concept? You can pay attention to this junk stock: $C3.ai(AI.US)$ There are no fundamentals.
